Emergency Message Dissemination Schemes based on Congestion Avoidance in VANET and Vehicular FoG Computing

Abstract:

With the rapid growth in connected vehicles, FoG-assisted vehicular ad hoc Network (VANET) is an emerging and novel field of research. For information sharing, a number of messages are exchanged in varied applications including traffic monitoring, area specific live weather and social aspects monitoring, it is quite challenging where vehicles’ speed, direction and density of neighbors on the move are not consistent in this scenario and congestion avoidance is also quite challenging to avoid communication loss during busy hours or emergency cases. This paper presents emergency message dissemination schemes that are based on congestion avoidance scenarios in VANET and vehicular FoG computing in the similar vein, FoG assisted VANET architecture is explored that can efficiently manage the message congestion scenarios. We present a taxonomy of schemes that address message congestion avoidance. Next, we have included a discussion about comparison of congestion avoidance schemes to highlight strengths and weaknesses. We have also identified that FoG servers help to reduce the accessibility delays and congestion as compared to directly approaching cloud for all requests in linkage with big data repositories. For the dependable applicability of FoG in VANET, we have identified a number of open research challenges.
